Distributed Quantum Networking with Trapped Ions

Trapped ions are a leading modality for both quantum computing and quantum networking due to their long coherence times, high fidelity two-qubit gates and high ion-photon and ion-ion entanglement fidelities [1-3]. Networking multiple trapped-ion QPUs will allow a scalable and modular framework on which to perform deeper and more useful algorithms. In this talk we present the high-level design and operation on an interconnected trapped ion quantum computer capable of transmitting entangled photons both locally and over a fiber network as well as performing local qubit operations. We will show recent results on photonically mediated remote entanglement of qubits that will allow the system to perform distributed quantum networking.
